<\/a><\/figure><\/div>\n\n\n\n1. Type de filetage : les filets cylindriques sont des filets m\u00e9triques et les filets coniques sont des filets NPT.
2. La qualit\u00e9 d'ajustement des filets m\u00e9triques doit \u00eatre de 6g\/6H ou sup\u00e9rieure, conform\u00e9ment \u00e0 la r\u00e9glementation en vigueur, et l'\u00e9paisseur restante de la paroi au point le plus profond de tout chanfrein ou de toute rainure de d\u00e9gagement du filetage int\u00e9rieur ne doit pas \u00eatre inf\u00e9rieure \u00e0 2 mm.<\/p>\n\n\n\n
3. Les filetages ext\u00e9rieurs NPT avec brides ou bouchons obturateurs doivent avoir une longueur effective de filetage au moins \u00e9gale \u00e0 la dimension \u201cL2\u201d, et la longueur entre la face d'extr\u00e9mit\u00e9 de la bride et la queue du filetage ne doit pas \u00eatre inf\u00e9rieure \u00e0 la dimension \u201cL4\u201d.
4. Les filetages internes NPT doivent \u00eatre mesur\u00e9s \u00e0 l'aide d'une jauge \u00e0 bouchon L1, de \u201centerr\u00e9\u201d \u00e0 \u201c2 tours\u201d.
5. La longueur de la section du filetage ext\u00e9rieur doit \u00eatre d'au moins 8 mm et comporter au moins 8 pas de vis. Si le filetage comporte une rainure de d\u00e9gagement, une rondelle int\u00e9gr\u00e9e et non compressible ou un dispositif \u00e9quivalent doit \u00eatre assembl\u00e9 pour assurer la longueur d'engagement du filetage requise.
*Les bouchons d'\u00e9tanch\u00e9it\u00e9 Ex NPT ne doivent pas avoir de bride.
# Compte tenu de la possibilit\u00e9 d'un chanfrein ou d'une rainure de d\u00e9gagement lors de l'installation dans l'entr\u00e9e de l'\u00e9quipement, l'exigence de 8 pas de filets vise \u00e0 garantir l'engagement d'au moins 5 pas de filets.<\/p>","protected":false},"excerpt":{"rendered":"
